Pyromancer's Goggles + Reverberate

Pyromancer's Goggles

Reverberate

How it works

1. Cast any instant or sorcery by paying its mana cost.
2. Holding priority, activate Pyromancer's Goggles by tapping it, adding .
3. Cast Reverberate by paying its mana cost, targeting the instant or sorcery cast in step 1.
4. Pyromancer's Goggles triggers, copying Reverberate, with the copy targeting the original Reverberate.
5. Resolve the copy of Reverberate, creating a copy of Reverberate targeting the original Reverberate.
6. Repeat step 5.

This looping marvel centers on Pyromancer's Goggles, whose triggered ability is uniquely primed to copy any red instant or sorcery fueled by the mana it produces. By casting Reverberate to copy an initial spell, you trigger the Goggles because the mana used to cast Reverberate came from the artifact itself. This creates a reflexive loop where you target Reverberate with its own copied iteration, generating infinite magecraft triggers as the copies continuously bounce off one another in a recursive spiral of magical replication.
